Joiner, Sweetwater, Tex. 7 Application June 8,1943, SerialNo.490,08f7j 3 Claims. (crass- 58) This invention relates to a combined closure andair hose dummy, and it is an object of the inventiontol provide an air hose dummy coupling includinga rubber gasket to assure a tight connectiontwhen the dummy coupling is applied and whereby a tighter closure is effected as the dummy coupling interlocks with the hose coupling head.

It isan important object of the invention to provideadummy coupling to be applied at the t rearI end of a train and which serves to so close orseal the air line as to eliminate air leakage.

In connection with freight trains, the angle cock valve of thecaboose is, turned with great frequency resulting in relatively rapid wear due to rust, grit and other foreignmatter scratching the sidewall of thevalve when the valve is opened up to let air out after the train has reached its destination and the engine istaken oif. The air pressure in the line is of such power as to cause the sand and the like to ,cut the valve as it opens. It is a purpose of the present invention to provide a dummy coupling which will obviate these disadvantages and thereby materially prolong the life of the parts of the air system, such as the angle cock valve, and also the parts of the air pump or compressor on thelocomotive, as with -'the use of my improved dummy coupling there will be no air leak and particularlywhen the air has reached that pressure, as eighty pounds in the train line, at which the pump will automatically stop.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved combined closure and air hose dummy whereby certain important advantages are attained, as will be hereinafter more fully set forth.

In order that my invention may be better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a fragmentary view in elevation i1- lustrating a dummy coupling constructed in accordance with an embodiment of my invention and in applied position.

Figure2 is an enlarged sectional view taken substantiallyonthe'line 2-2of Figure 1, the regular coupling being indicated by broken lines.

Figure 3 is a view in top plan of the dummy cou- Pling as illustrated in Figures 1 and 2.

Figure 7 is a fragmentary view in side elevation of the structure as illustrated in Figure 6.

' Figure 8 is a view partly in section and partly in elevation illustrating a coupling constructed in accordance with a still further embodiment of the invention, and in applied position, and

Figure 9 is a view in top plan of the dummy coupling illustrated in Figure 8, unappli'edt In the embodiment of the invention as illustrated in Figures 1 to 3, l denotes an air hose section at the rear or caboose end of a train and which carries a coupling head H of a conventional type and with which is adapted to be interlocked the dummy coupling D to effectively close the air line. This dummycoupling D includes a head 2 similar to the conventional head H and is provided in its central portion with a rubber gasket 3 for coaction with the rubber gasket 4 of the head H when'the dummy coupling D is applied,

thereby providing a rubber-tight fit which assures an effective seal and thus eliminates such leakage of air which might result in an emergency application with resultant damage to equipment due to a quick stop.

The head 2 of the coupling D has an outstanding shank portion 5 closed against new therethrough and this shank 5 is extended to provide a handle 6 to facilitate the application or removal of the coupling D. The outer or free portion of this handle 6 is provided with an opening 1 to allow convenient coupling with the handle 6 of an end portion of the dummy chain 8 for supporting thedummy coupling when not in use In the embodiment of the invention as illus- I trated in Figures 6 and 7, the shank portion ll of the dummy coupling B is closed and the side of this shank portion H is provided with a laterally directed eye member l2 to which the dummy chain may be readily connected.

In the embodiment of the invention as.i1lus-' trated in Figures 8 and 9, the dummy coupling A comprises an elongated and relatively narrow bar or member provided with the well known locking flanges l4 and for coaction with the coupling head H. Adapted to tightly interlock with the rubber gasket l6 of the coupling head H is the rubber gasket I! carried by and extending beyond the outer face of an annular plate I8. This plate [8 is provided with a central recess orsocket 19 in which the gasket ll snugly fits and the lower or inner portion of the side wall a of this recess or socket I9 is undercut to provide an annular recess or channel 20 in which is snugly received the outstandin surrounding flange 2| carried by and integral with the rubber gasket ll.

By the use of a dummy coupling including a rubber gasket for coaction with the rubber gasket of the usual or standard coupling head, the dummy coupling can be readily and easily applied or removed and when applied, assures such an interlocking connection to prevent leakage and which is more effective in e h n he closing by the usual conventional angle cock valve.

From the foregoing description it is thought to'he obvious that a combined closure and air hose mmy constructed in a c rdance with my invention is particularly well adapted for use by reason of the convenien e and f cility with which it may be a sembled and operated.

What is claimed is:

1. A dummy air hose coupling, comprising .an elongated member having locking flanges djacent vone end for connection with corresponding flanges of a standard coupl ng. th member having a su tantial y flat face betwe n the l ok ing flanges, said face having a circular recess.

2. A dummy air hose coupling, comprising a relatively long flat plate body having a portion of one end obliquely extended to form a looking flange, a second locking flange integral with the side of the plate body remote from the first flange, the locking flanges being designed for connection with corresponding flanges of a standard coupling, the side of the plate from which the second mentioned flange extends and ying betw en the flan es, b n desi ned t be positioned in opposed relation with the gasket of the standard coupling, an annulus secured to the i said side of the plate between the flanges, the annullls being closed upon one side by the plate,

the annulus having a circular channel cut in the inner iacethereof, and a gasket fitted tightly in the annulus and having an encircling rib secured in said circular channel, the gasket extending beyond the side of the annulus remote from" theplate for tight engagement and coaction. w th h a ket of, the standard coup ine- 3,. A dummy air hose coupling, comprising a relatively long plate member having integral locking flanges adjacent one end for connection with corresponding flanges of a standard coupling, a face of the plate between the locking flanges having an area designed to position in opposed relation with the gasket of the standard coupling when the locking flanges are connected with the said corresponding flanges of the standard coupling, an annulusfixed to the plate over said area, the annulus having a circular channel out in the inner face thereof, an eye for-m- P ing member integral with the plate upon the SYLVES'TER L.
